. To all whom it may concern:

Be it known that 1, Thomas F. MoCALLIster, a citizen of the United States, residing at Prineville, in the county of Greek and State of Oregon, have invented certain new and useful Improvements in Power-Transmission and Driving Mechanism for Automobiles, of which the following is a specification.

Thi invention relates to automobile gearing, and pertains especially to powertransmission gearing involving a combination of frictional and gear wheels for shifting and transmitting the driving power of automobiles. V j l The object of the invention is toprovide an improved combination and arrangement of frictional and gear wheels or pinions mounted on a pair of independent shafts and cooperating with a drive wheel having frictional and toothed faces, for transmitting power.

A. further object of the invention is to provide a motorvehicle with means formoving the wheels with its own power from stalled position, such means comprising 'a shaft driven by the motor or engine of the vehicle, and a drum or Windlass mounted on and operated by said shaft in connection witha chain or rope having one end fixed or anchored and the other end attached to the drum or cable.

A still further object of the invention is to provide a motor vehicle with a supplemental shaft adapted to be coupled with the motor or engine shaft and having a belt pulley for operating various machines, such as sawing, threshing, pumping, &c.

A still further object of theinvention is to provide a motor vehicle with special power transmission mechanism for propelling the vehicle at various speeds, forreversing, for derrick or stalledpurposes, and for operating various machines by supplemental shaft, pulley, and' belt connections with the propelling mechanism of the motor vehicle, and to furnishnoveland peculiar means for shifting said'mechanism so that the motor power may be transmitted and used for various purposes, as will be hereinafter fully explained. V V

A still further object of the invention is to provide for the location of the transmitting mechanism adjacent to the rear end of the engine, and to have a supplemental Specification of Letters Patent.

Application filed February 27, 1917. Serial No. 151,277.

to the said mechanism for the purpose of utilizing said shaft for operating a drum or Windlass, or for operating a belt pulley.

In the accompanying drawings forming part of this application Figure 1 is a top view of part of an automobile showing the application of the invent-ion, the dotted lines A indicating the shaft extension to the front wheels.

Fig. 2 is an elevation looking at one side of-the transmission mechanism.

The same reference characters denote the same parts throughout the several views of the drawings.

In'order to afford means for producing various speeds as desired, and for transmitting the driving power of the engine, I employ a multiple gear wheel 1, mounted adjacent to the engine 9. The wheel is of special construction, having anannular inner gear 3 on the engine shaft side thereof, a similar gear 4: on the other side ofthe wheel opposite the gear 3. The wheel is also provided on the engine shaft side with an outer gear 5, and the other side of the wheel has a similar outer gear 6 opposite the gear 5. The engine shaft side of the wheel is provided with an annular frictional or smooth face 7 off-set annularly from the gear 5 to the periphery of the wheel, so that the gear 5 is centrally between the frictional bearing face 7 and the gear 3, all of said gears being concentric.

I employ a pair of shafts, one on each side of the wheel 1, and extend said shafts acrossthe faces of the wheel perpendicular tothe wheel shaft 8. The primary shaft 9 of the pair of shafts is located just above the shaft 8, and constitutes the engine shaft. The other or auxiliary shaft 10, of said pair, constitutes a drive shaft which is geared with the rear axle 11 of an automobile. The shaft 10 has fixed thereto clutches 12 and 13, and-driving pinions 15 and 16 are slidable on the shaft, and -have a clutch-en-' gaging face 17 cooperating with the "clutches l2 and 13, for shifting the pinions with 'respect to the wheel gears 6 and 4. respectively, for various speeds. The shaft hasa reversing pinion l8 keyed to and slida ble on theshaft, and is provided with" a a clutch member 19 cooperating with a clutch 20 secured to the shaft 10, for-shifting the pinion.18:into and out of gear Wlbll the wheel gear 4, in reverse movement, said clutches are fixedatlO to the shaft 10.

' The, primary or engine shaft 9 has .a pair of clutches 21 and'22 fixed thereto at 11,

"gine.

i the shaft, at 9 and which is made to en-..

gage the friction face 7 of the wheel 1, as desired or as occasion may demand.

1 sides of the wheel have annular cut outs 27 a drum or Windlass 29: mounted thereon, or.

between the various gears or toothed portions of the 'wheelso as to permit sliding movement of the various pinions without interference.

It will be seen that one side of the wheel 1 cooperates with certain of the pinions of the shaft 10, for driving this shaft, that;

the other or opposite face of the wheel 00-, operates with certain of the .pinions on the shaft 9 for driving or revolving the wheel, that the wheel may be driven or revolved in either direction as desired or as occasion may demand, by operating the reversing pinion, and that theother pinions are shifted with respect to the center of theywheel -1, for varying the speed of the machine. Another important function or purpose of the wheel 1, is to'have it operate the shaft 8 uponwhich it is mounted, for operating certain other elements by means of the driving power imparted to the wheel from the engine of the machine. This I accomplish by extending the shaft 8 from one side of the wheel at right angles to the shaft 10, and under the shaft 9.- The shaft 8 may revolve the Windlass may be coupled by a clutch 29 to the outer end of the shaft 28. Obviously the Windlass and a rope or cable may be op erated by the wheel 1, for moving a stalled automobile or truck, and for derrick or other such purposes. The'shaft coupling 30 is such as to afford means for attaching a sup plemental shaft 31, having a pulley 32 from driving a belt in operating various machines, especially such as usually require separate engines or motor power for farm and ranch work; Obviously .a sprocket;

The 7 wheel may be substituted forthe pulley in "the event of using a sprocket chain. In 0perati-n g the'se supplemental elements, the

pinions of the shaft 10 are shifted,- out of 'gear with the'w'heel' 1, and the engine shaft '9' drives the said wheel by reason of. the

'gear 'pini'on's meshing with the wheel gears; The -supplemental;cross shaft 28 is suitably ournaled on the frame of the machine or automobile so asito-rcentralize'lthe wheel 11 as nearQaspOssibIeWith r' espe'ctto the engine 'andthe engineshaft :The driving shaft; l'O para-llels the shafts) on} the opposite side 1 of the .iwheel l, :and the 1 latter is .revolved CBHHQLlQly bGUYEQIi the, shafts 3 :9Fand .111), and
